LOUIS II. REPPELL, OF KANSAS CITY, MISSOURI.

BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 442,548, dated December 9, 1890.

Application led October Il, 1889. Serial No. 326,707. (No model.)

To ctZZ whom, t may concern;

Be it known that I, LoUIs H. REPPELL, of Kansas Oity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Briek-Kilns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improvementin brick-kilns whereby the heat from the furnace may be properly distributed throughout the kiln, and whereby the cold air may be properly distributed throughout the kiln, in order to dry off the brick after they have been set; and my invention consists of features of novelty hereinafter described, and pointed out in the claims.

Figure I is a vertical longitudinal section of my improved kiln-furnace. Fig. II is a horizontal section taken on line :11;15, Fig. I. Fig. III is a transverse section showing the various openings in the furnace. Fig. IV is a perspective view showing a series of the furnaces and a section of the kiln-wall in the rear. Fig. V is a perspective view of the kiln- Fig. VI is a horizontal section showing the peep-holes into the kiln. Fig. VII is a perspective view of one of the brackets for holding the door-frame.

Referring' to the drawings, I represents the side wall of the kiln, against which a series of furnaces 2 arebuilt. rlhc :furnaces are built double, each furnace supplying two openings into the kiln. The whole series of furnaces are built up solidly, as shown in Fig. IV.

3 represents the Vlire-chamber of the furnace, e the fuel-opening, and 5 the door to the saine.

6 :represents the ash-pit, over which are placed the usual gratings 7.

8 represents the damper, by which the opening into the ash-pit may be closed. In the side walls of the furnace I form air-conduits 9. The air-conduits extend along each side of the lire-chamber and along each side of a combustion-chamber l0, situated at the rear of the fire-chamber. (See Figll.) Theair-conduits extend through the front wall of the furnace, as shown in Figs. II and IV.

ll represents a series of lateral openings from the air-conduits into the fire and combustion chambers, which permit the air to enter into the same, as shown by arrows in Fig. II. By the use of suitable means-such as a brick, for instauce-the front openings of the air-conduits Amay be closed if the furnaces should become overheated; or if one side of the furnace should become hotter than the other side, then one of the air-conduits can be closed until the heat has become evenly distributed.

12 represents aseries of peep-holes extending through the furnaces into the kilns, by which means the operator can see and judge of the amount. of heat the bricks in the kiln are being subjected to and regulate the furnaces accordingly.

Leading from the rear of the combustionchamber are heat and air openings 13 I4 from the furnace into the kiln. The lower openings 13 extend some distance into the interior of the kiln, as shown at l5.

I do not confine myself to any certain distance to which the openings I3 may extend, for if it is found desirable they may extend to the center of the kiln. The openings l-I are placed above the openings lf3 and discharge the heat and air direct into the side of the kiln.

16 represents a damper by which the openings 13 l-l` may be closed entirely, or partly so, as may be desired. I have shown this damper composed of an ordinary tile, a chain I7 attached thereto, said chain extending out through the roof of the combustion-chamber, and pins 1S attached to the side of the kilnwall, to which the chain may be attached in order to h old the damper in any desired position; but I do not confine myself to this form of damper orthe means of operating the saine.

19 represents a loose tile in the roof of the combustion-chamber, through which the chain` 17 passes. This tile may be readily removed if it is desired at any time to remove the damper from the furnace.

20 represents a series of brackets secured to the front wall of the lfurnaces. rIhe brackets are provided at their upper ends with shoulders 2l,into which rests a bar 22,which extends along the front of the furnaces. The bar 22 also rests on shoulders 23 on the top of IOO the door-frames, the door-frames being thus connected and held iirmly in their proper places.

By the use of the damper 1.6 I can permit the heat and air to pass in through both of the openings 13 l4,if desired; or if the upper part of the kiln should become too hot I can regulate the size of the openings 14, or close the same entirely, if desired, thus throwing the heat to the center of the kiln through the openings 13 and allow the overheated upper portion to cool down to the proper degree of heat. By the same means I can regulate the size of the openings 13 or close the same entirely, if desired.

By the proper use of the damper I am enabled to prevent any of the brick from becoming ire-fiashed and thus ruined for certain purposes.

After the kiln has been set I raise the dampers up,permitting plenty of fresh air to pass into the kiln to drive out the Water-smoke and properly dry the brick, thus preventing the brick from becoming steamed and softened, which causes them to crack and become shaky and rendered unfit for use.

I claim as my invcntion- 1. In a brick-kiln, the combination of the body of the kiln,irechamber 3 and combustion-chamber l0, tWo contiguous conduits 13 14, leading from the combustion-chamber to the kiln, one of said conduits 13 extending into the body of the kiln, and a single damper for regulating the draft in the two conduits 13 14, being adapted to close one and leave the other open, or to close or open both, substantially as described.

2. In a brick-kiln, the combination of the bod;T ot' the kiln,a furnace having a tire and a combustion chamber, contiguous conduits or tlues 1.3 14 on each side of said furnace, leading from the combustion-chamber to the kiln, one of said conduits extending into the body of the kiln, a damper 16 for regulating the draft in said conduits, and chain 17 for controlling the damper, said chain passing through loose tile 19 in the roof of the combustion-chamber and being attached to pin 13 in the side of the kiln-Wall, substantially as described.
